wheels on an AT "Tubeless" My DCT AT was converted from new 35.000 KM ago with no problem. For peace of mind, I fitted a pressure monitoring system to check the pressure in both wheels. As of today, I have never had a problem. Works for me. |

https://www.youtube.com/watch?v=--Ucwqhd0tI Maybe different markets receive the bikes with different rims? (i.e. just leave out that internal rubber fitting and fit a tube instead). |
Quote:
The Honda Crosstourer is fitted with a spoked rim that looks like a Behr arrangement, with spokes to the outer edge of the rim, front and back. Tubeless? Don't know, but they look like it. |

Woody's Wheel Works (USA) I believe has resumed doing tubeless conversions but still won't do a front wheel, only rear. Fine for me as front is pretty easy to spoon off and replace a tube ... and anyway ... seems we always get a REAR flat! Not a Front! :censored: BTW, I followed a tutorial using a high quality Marine sealer to make my DR650 rims tubeless. I could not get it to work. Not even sure from where it was leaking ... but obviously I did something wrong. The newest Tape kits seem to work much better. KTM's solution seems fraught with possible problems. IMO, the wheel needs to be Spoke Free (meaning spoke NOT going into inside of air tight wheel area) to have a proper tubeless set up, even though many are doing well with latest Tape kits. I'd need a PRO to do it for me ... I apparently suck at such operations! doh |

Spoked wheels are derived from the invention of the bicycle (which initially had solid wheels and evolved into a spoked arrangement as the technology moved along) - and that is the key to it. Modern technology can produce a cast wheel well within tolerances. light enough in weight and to budget to do the job for, say, 99% of the population. Tyres ditto. Job done, PhD earned. :innocent: |

for adventure, off-raod use I'd rather have spoked wheels any time of the day and night. When you crack you cast wheel in the middle of nowhere you pretty much done, not so much with spoked wheel. Not to mention absorption of bumps and S#$% on the road is far better with spokes wheels. |

While modern cast wheels can be (some) much stronger than those from 20 years back, they still can have vulnerabilities. Yes, we all agree changing a flat rear tire is no picnic, can ruin your whole day. But this skill is something ALL ADV travelers need to master and MUST have the tools and ability to do this in a pinch. For me, I will ride on a flat for miles to get to a tire repair guy, yes, I hate doing rear flat repair! doh And ... I really SUCK AT IT! doh Some tires on some bikes can be very tough to break the bead on. But if you seriously crack your tubeless cast wheel you could have even more serious problems. If the cast wheel totally breaks apart ... then what? :innocent: Spoked wheels provide a bit of Flex and shock absorption. Cast wheels not so much. Many times a spoked wheel can be pounded back into shape. Cast wheels, not so much, but I did have my Vstrom DID cast wheels repaired twice from hard hits in Baja, one finally cracked, could not be repaired. The Vstrom was so common I was able to find a replacement on the forums for about $150, IIRC. But the OEM's are showing the way forward with their spoked, tubeless wheels. Some use the Center rail spoke attach point (Aprilia, Yamaha, et al), others are BMW style where spoke attaches on outer edge. KTM have reinvented the wheel with their system ... and IMHO, is not great! (time will tell!) I have seen BMW tubeless wheels destroyed off road on two occasions. On one occasion, we lent rider a tube, he was able to continue. A new wheel cost him something like $800. Something else to consider: Ever tried putting a plug into a knobby tire? Depending where the puncture is ... it is not always straight forward. bier |
Let's revisit what I wrote...
Spoked wheels might have some advantage if you are racing but if you are adventure touring then in my opinion there's no reliability disadvantage with an alloys/tubeless mix When I'm adventure touring I am often thousands of miles from home and I ride like I want to get back with the bike in one piece, so considerately! IMO you really have to do something stupid to crack an alloy. I have only met one guy who did that (Nadhim from UKGSer) who ran over a kerb at 70mph and cracked both front and rear. By comparison the tubed rims fitted to most bikes (e.g. BMW F800GS) seem to be made of chocolate and vary dramatically from the high quality Excel rims you might fit if racing. Alloy wheels also have the advantage of lower unsprung weight. I've explored the ideas of sealing tubed rims to make them tubeless, the real danger in this is that the tubed rim profile tends to lack the tubeless safety bead near the lip of the rim which is there to keep the tyre on the rim in case of a blowout. http://www.morocco-knowledgebase.net/tim/tubed_plug.jpg Tubeless knobbly plug |

The XT versions have developed a double flange arrangement for the wheel rim; maybe another way to get around some patent or other? It makes for an "interesting" pattern of spokes laced to those rims. https://www.rustsports.com/metal/suz...650xt_405.html According to the article linked here, these suit 98% of riders. :innocent: |

Years past, did many "group" Baja rides, going back to late 1980's. On these rides we've seen guys do really stupid things on totally inappropriate machines. In groups we see over zealous, testosterone addled numbskulls. This is where I saw broken BMW tubeless spoked wheels and worse. But on longer tours most riders are more sensible so very little problem with cast wheel. But "stuff" can and DOES happen. I really like the Suzuki system shown above ... but I've no idea how this new system will work. But it's a DID product so I expect it's very good. Quote:
The spoked/tubed DID wheels on my old DR650 are quite tough. I've dented a two of them from going too fast, but was always able to continue. I agree, some Behr wheels have been bad, very soft. Also, not all Excel wheels are all that tough. For them, lightness is highest priority. They have different spec'd ones, not all are dent resistant. On a Motocross track, there are NO rocks and nothing to hit. In Hare Scrambles and Enduro we hit LOTS of things ... hard! Guys I know (rode AMA Enduro in 80's/90's) like DID Dirt Star wheels. In the Dakar DID Dirt Star also popular. :D:D:D Quote:
Other bikes may not have such secure safety beads. But if they are DID wheels (many are in Japanese dual sport range) they probably have some form of safety bead to prevent tire coming off rim in event of flat at high speed. Quote:
Also, if plug goes in through big knobby, riding hard off road may have that plug pulled out. I've never seen this, but seems it could happen if plug is in a not so ideal place. bier |

If you do only on road touring then yes, alloys are fine and even easier to clean. |
